This easy version of a one dish meal uses some of my favorite convenience foods. Don't turn up your nose at convenience foods; this type of recipe used to take a couple of hours to make! And, having grown up with the original, I can say with confidence that this twist on the classic recipe is just as good.
All you need with this recipe is a nice green salad tossed with some avocados and grape tomatoes and drizzled with a tangy vinaigrette. Enjoy every bite of this fabulous meal.

To Freeze Ahead

Store the mashed potatoes in the refrigerator and the Parmesan cheese in fridge.
To Thaw and Reheat
To thaw and reheat, thaw the casserole overnight in the refrigerator.

Glass Bakeware Warning
For premade casseroles or leftovers that are in a glass baking dish and have been refrigerated, do not place directly into a hot oven as the glass can shatter. Instead, place any cold glass bakeware into a cold oven to warm up while it preheats. Or, allow the bakeware to rest outside of the fridge for 30 minutes to reach room temperature while the oven preheats.
